As watershed models become increasingly functional and useful, there is a need to extend their applicability to other locations to explore the possibility of calibrating and evaluating them in such new locations. This study used the “abcd” monthly water balance model for three catchments in different places in the United States in order to investigate the feasibility of this model in different regions. Although the regional calibration led to nearly perfect regional relationships between catchment model parameters and basin characteristics in catchments with little or no snow, practicality of this model in regions dominated by snow was questionable.
